Boasting one of the most impressive winning streaks in recent times with six consecutive victories, the Paraense fighter occupies the eleventh position in the featherweight ranking (up to 65,7 kg), while the Briton is seventh. A victory could catapult the Brazilian to the top of the pack, placing him as one of the title shot contenders . On the other hand, coming off a loss to Jean Silva , Allen needs to win again to avoid becoming the division's "gatekeeper".
